WebA quadratic sequence is an ordered sequence of numbers: s1, s2, s3, …. The numbers s 1, s 2, s 3, … are called terms of the sequence, and the subscripts 1, 2, 3, … are the indices (values of the index). A quadratic sequence satisfies a quadratic equation where the terms are the y-values and the indices are the x-values. Webhowever, you might notice that the differences of the differences between the numbers are equal (5-3=2, 7-5=2). that means the sequence is quadratic/power of 2. since the sequence is quadratic, you only need 3 …
